Controlling TreeView Expand/Collapse
With a TreeView bound to an XML file as below I want to obtain the
functionality where Chapter 2 and 3 are forced to collapse when Chapter 1 is
selected and Chapter 1 and 3 collapses when Chapter 2 is selected and so on.
Any Ideas on how to solve this in a smart way?
Data bindings
<asp:TreeView id="BookTreeVie w"
DataSourceID="B ookXmlDataSourc e"
runat="server">
<DataBindings >
<asp:TreeNodeBi nding DataMember="Boo k" TextField="Titl e"/>
<asp:TreeNodeBi nding DataMember="Cha pter" TextField="Head ing"/>
<asp:TreeNodeBi nding DataMember="Sec tion" TextField="Head ing"/>
</DataBindings>
</asp:TreeView>
<asp:XmlDataSou rce id="BookXmlData Source"
DataFile="Book. xml"
runat="server">
</asp:XmlDataSour ce>
The XML file
<Book Title="Book Title">
<Chapter Heading="Chapte r 1">
<Section Heading="Sectio n 1"/>
<Section Heading="Sectio n 2"/>
<Section Heading="Sectio n 3"/>
</Chapter>
<Chapter Heading="Chapte r 2">
<Section Heading="Sectio n 1"/>
<Section Heading="Sectio n 2"/>
<Section Heading="Sectio n 3"/>
</Chapter>
<Chapter Heading="Chapte r 3">
<Section Heading="Sectio n 1"/>
<Section Heading="Sectio n 2"/>
<Section Heading="Sectio n 3"/>
</Chapter>
</Book>
